A Short 310-A4 torpedo-dropping seaplane, which was apparently recovered at sea by the Donna Nook of Fleetwood. Named from the 310 h.p. Sunbeam Cossack engine which powered it, the 310-A4 first flew in July 1916, and most of the 127 built were used for long-range patrol work. With a crew of two and a pair of 230 lb bombs the aircraft had an endurance of six hours.

This Rolls-Royce Eagle-powered anti-submarine/Zeppelin patrol flying boat had a crew of four and was armed with up to four Lewis guns. It could carry either four 100 lb bombs or two 230 lb bombs beneath the wings.
